Framework for Polarized Magnetic Neutron Scattering from Nanoparticle Assemblies with Vortex-Type Spin Textures
Michael P. Adams, Evelyn P. Sinaga, Stefan Liscak +1
Within the framework of the recently introduced multi-nanoparticle power-series expansion method for the polarized small-angle neutron scattering (SANS) cross section, we present a…

Neutron-scattering signature of the Dzyaloshinskii-Moriya interaction in nanoparticles
Evelyn Pratami Sinaga, Michael P. Adams, Eddwi H. Hasdeo +1
The antisymmetric Dzyaloshinkii-Moriya interaction (DMI) arises in systems with broken inversion symmetry and strong spin-orbit coupling. In conjunction with the isotropic and symm…

Signature of surface anisotropy in the spin-flip neutron scattering cross section of spherical nanoparticles: atomistic simulations and analytical theory
Michael P. Adams, Evelyn Pratami Sinaga, Hamid Kachkachi +1
We investigate the signature of magnetic surface anisotropy in nanoparticles in their spin-flip neutron scattering cross section. Taking into account the isotropic exchange interac…
